It seems that when the chain jumped, the door closed (and dragged the chain with it) about a foot or so.
So here is my delima... I need to tell this garage door opener, to release the chain about a foot to grab the door and make it open and close normally again. As it sits right now, when I close it, it stops about a foot off the ground. I had to release the door for tonight to secure the garage - but would like to know if anyone has any instruction on how to fix this problem.
ANY help is GREATLY appreciated.
